PAPER FASTENER.

Application illed November ll, 1921. Serial lilo. 512,685.

To all whom it may concern Be it known that l, HERMAN A. LIND- srnoiu, a citizen of the United States,.residing at Seattle, in the county of King and State of Washington, have Invented anew and useful Paper Fastener, of which the following is a specification.

My invention has reference particularly to improvements in paper fasteners of the flat it) metal variety adapted to be inserted through papers to be held, and then bent into'operative position; and the objects I seek to achieve are, the provision of a fastener wherein the points of the prongs are covllt] ered when in place, thus aflording one that presents no sharp points to catch on or mar adjacent objects; and, a special punch for this fastener, whereby openings may be pierced in said paper in a proper position to to accommodate the same.

lln the accompanying drawings- Figure 1 is a perspective of the fastener complete.

Fig. 2 is a plan view of the same as ap- 25 plied to and fastening sheets of paper.

Referring more particularly to the drawings, l designates the body of the fastener, made preferaby of sheet brass, bent at one end into a right angular prong 2, and the to other end bent into a right an ular and shorter prong 3; 4 designates a sllde of the same material mounted on the longer prong, the whole comprising the fastener complete. 5 denotes a pair of slits throu h sheets of 35 paper, and dla onall located with reference to the corners t ereol. These slits are made through the paper by the use of the punch heretofore referred to, and which ll contemplate making the subject of another applicaac tion.

To place the fastener "in position, the

prong portions are inserted to their limit through the slits from the under side of the aper, and the slide 4 then placed on the 45 onger prong. The shorter prong 3 is then bent down in contact with the upper side of the. paper, as indicated in Fig. 2, the longer prong 2 bent so as to contact with the first prong, and then the slide 4 is moved along so the prong 2 so as to embrace prong 3 and to cover the pointed terminal of pron 2. As shown in ig. 2, the pointed termina of prong 3 is covered by the prong 2, and the slide'covers the point of said last named prong, thus efi'ectually covering the pointed resiliency of the metal ordinarily is sufficient to keep the slide in place. llf it is desired to further lock the slide, it can be done by striking out of the metal of prong 2 a small upwardly extending integral point 6, which will fit into a complementary recess in the slide, denoted by 7 in Fig. 2; said point and recess coming together when the s'ide is in the position shown in said figure.

in utilizing the ordinary brass fastener provided with a pair of contactin prongs adapted to be spread in opposite directions, the contiguous prongs act as a pivot on which the several sheets will turn, and the papers are not held securely in position. To make their use eflective in this respect, two fasteners are necessary. lln any use, the free ends of the prongs tear or catch on adjacent papers or objects. These objectionable features are particularly noticeable in placing or removing papers from files, wherein the second sheets are usually of material easily torn, and the exposed prongs catch on and withdraw papers other than the ones intended.

This fastener, by reason of its contact with the double slits in the paper, permits no pivotal play, and a single fastener at the corner 0 sheets of paper as shown, and as it is rimarily intended to be used, is suilicient to liold the papers securely together and in alignment, at the same time exposing no sharp points. llts construction is such as to enable it to take the place of two of the usual brass fasteners, and to function in a better way.

ll claim:

1. A paper fastener, comprisin a body having at one end a prong angu arly disposed at the other-end a lor pron. angularly disposed and located 0 posite y of the first prong, and a slide le member mounted thereon, ada ted to embrace said prongs and cover the rec end of the longer prong when the longer prong is bent in operative position over the shorter prong.

2. A ner, compg a flat CID g nnmooo hwy having one enoi e pron diisposed nv'; thereon having on interionly ioce'teci necess right angles to the body, at b e other end to en ege said point, seidi member adopt-ed o longer prong, disposed at right angles to to em oreee the shorter prong, to cover the N the body and located oppositely of the first free end of the other prong and to lock 5 prong, provideoi with an integral point adtherewith, when the fastener is in operative jacent its pointed terminal and projecting position.
